Yes, a couple of years ago our agent showed us where our homeowner's policy had that provision. I have concerns about turning off city water, or using very little electricity due to that abandoned/vacant thing.
Coachmen still shows several floorplans on the Chevy 4500 chassis. Of course, Coachmen is owned by Forest River.
Our 2012 Coachmen is on the Chevy 4500. I love the chassis, but am not too happy with the build quality of the coach.
Our Leprechaun is a 2012. The layout is great for us, and the Chevy chassis has been problem free. However, the build quality of the coach is not very good. We've had plumbing leaks due to a screw run through a pipe during construction, leaks due to cheap connectors on the pex pipes, and roof leaks due to no caulking or gaskets on the marker lights. We still have one roof leak we haven't been able to track down. It feels like Coachmen used the cheapest parts, and the cheapest engineering they could.
This is by far not our first RV, nor is it our first Coachmen. It will be our last.
I agree completely with what Grumpy said.
In our Leprechaun (different model and different year) there is a wooden grill at the base of the kitchen cabinets. Above the grill is a sticker that reads "Low Point Drains". The three hoses that Grumpy talked about and their valves are behind that grill. The blue one is the fresh water tank drain in ours. The fresh tank is under the fridge, right next to this grill.
Don't know if this will help in your search.
